SPECIFICATION forming part of LettemPatent No. 381,002, dated April 10, 1888. i Application filed December 8, 1887. Serial No. 257,334. (No model) I K tion, reference being had to the accompanying drawings which form a part of this application, and in whichvice. Fig. 2 is a side elevation of the same. Fig. 3 is a section on theline x on, Fig. 2.

1 is the main or draft beam of the cultivator,

to each side of which is secured by means of bolts 6 a bar, 2, which bars project rearwardly, and are preferably'curved downwardly at their rear ends in order to form shanks 3 for the shovels 4. These bars are bent outwardly from the beam, so as to bring the shovels at the proper distance asunder. The shovels 4 are the inside and forward shovels. The outside and rear shovels, 5, are secured to the draft-beam bynieans of bent bars 7, which are bolted to the beam on top of the other bars by means of the same bolts, and which bars are identical with the bars '2, with the exception that they are a little longer and are bent out ward farther, so as to bring the rear shovels on the outside of the path of the others. The bolts 6, which secure the bars 2 7 to the central beam, 1, are screw-threaded at both ends, and are provided witha set of nuts for each bar. The bolt is passed through the .bars 2 and the beam, and the former are firmly secured by the nuts 17 oneach side; Then the bars 7 are placed on these nuts over the projecting ends of the bolts, and are secured by means of the nuts 19. This is for convenience in removing one or both of the outsideshovels without disturbing the others. Passing through openings in the rear ends of the bars 2 7 and through the lowerends of the handles 8, which are outside of the bars 2,

is a rod, 9, which is screw-threaded at each end, as shown. Screwed on this rod between the bars 2 2 are two nuts, 10, one bearing against each of the said bars, and on the said rod outside of the handles 8 are nuts 11, one

bearing against each handle. These nutsYlO.

7 5o -11, when screwed toward each "other, firmly Figure 1 is a plan view of my improved de-' the row.

clamp the bars 2 andthehandles togethervand to the frame. The bars 7', which carry the g outside shovels, 5, are held in positionfin an L analogous manner by means of nuts 1213, one on each side; and it-will be noted that in my'devi-ce it is only necessary to lengthenthe rod 9 and the bolts .6 to enablethe attachment of any number of shovels.

- Thehandles are retained at thedesire d ins cl'ination by means of the plates 14, which are secured to the handles by means of bolts or.-

rivets 15 and to the shanks of the shovels 4 by means-of bolts 16.

Bolted to the lower endof each of the shanks by means of the bolts 21 is a loop, 20, which passes for securing the shovel in place. This 65. Y forms a vertical slot, through which a bolt, 22, I

vertical slot affords means whereby the shovel provided with a'.slot, 24., and which I insert between the shovel and the loop 20, with the" bolt 22 passing through thesaid slot 24, so as p to turn the shovel ata greater or less angle to The shovel is provided with a cen tral bead or semicircular 'rib ,-25, through which a slot is made .for the insertion ofthe bolt 22, andwhich isfor the purpose of affording a bearing for the head of said bolt when the shovel is turnedat a greater or lessangle to the central'beam.

It will be seen that theshovel may be-slanted in either direction by merely shifting thebutt of the wedge to the desired side by rotating it on the bolt 22. 1 i

. Having thus described my invention, the fo ls lowing is what I claim asinew therein anddesire to secure by Letters Patent: 1. The combination, with a fla' t 'shovel and ashank, of the bead 25 on said shovel, having a transverse slot therethrough, a slottedwedge inserted betweensaid shovel and shank, and- 2. In a cultivator, the combination, with the central draft-beam, of the bars 2, arranged one on each side of the said beam and having their rear ends bent outward therefrom and curved 5 downward for carrying shovels, the bolts 6,

passing through said beam and bars and having projecting screw-threaded ends, nuts 17 on said bolts clamping said bars and beam together, the bars 7, resting upon the nuts 17- 10 and having the bolts 6 passing therethrough,

and being bent outward and downward at their rear ends for carrying the shovels, and nuts 19 on the outer ends of the bolts 6, clamping bars 7 to nuts 17, a screw-threaded rod passing through said central beam and bars 2 7, and nuts on said rod on both sides of each of the bars 2 7, for holding them in place, essentially as set forth.
